+It's my understanding that this is solved (please re-open if I'm wrong).
+The problem was that ICryptoTransform.CanReuseTransform wasn't checked
+- and the same transform was re-used. Mono return false (most of the
+time) while MS returns true (most of the time).
+Each crypto algorithm implementation can return a different value (and
+this could change between fx versions). Even if we "fix" this in the
+future it wouldn't be safe to ignore CanReuseTransform as CryptoConfig
+can be used to remap algorithms to alternative implementation (e.g.
+hardware support) which transform could behave differently.
